hi
iam currently using vs.net 2005 to make a window form on c#
i notice the event dragdrop for the listview control and would like to know if it is possible to drag a row from a listview to another row in the same listview and triggering an event as i was hoping to use it the group the 2 rows together

Is this[^] the type of thing you're looking for?
For what it's worth, I found it by searching for "listview drag and drop" in Google.

This is what I have currently:
(1) My form
(2) My menu bar with all the clicks I want on it
(3) A text box docked at the bottom of the form
This is what I'd like to happen:
(1) On launch of the program -
(i) I'd like for the program to ask a question, such as "What is your name?"
(2) On the answer of that question based upon input from the text box
(i) The first question to disappear
(ii) A second question to replace the first question
But I don't know how to make the text box docked to the bottom of the form input the text into the application and make the application continue to accept the responses and keep replacing the original question with a new question, etc. Can anyone help me with this?

So you are trying to build a wizard type application.
Presumably you have the main form appear when you run the program. Some things you will need.
A list of questions
A list of expected responses/validation rules (eg ask name and get back numbers)
Somewhere to store these usually a database or an XML file
Some mechanism that tells you where you are in the list (index will do)
A container for responses, List<string> will do.
Flow
Form opens
Populate the question list
Set the current index to 0
-----------repeat here
display the text in a label for the question in list[0]
when the user clicks NEXT button validate the text in the textbox
store the response in the response List
increment the current index and repeat until all questions are responded to.
deal with the list of responses, store the info in your preferred device.
You then need to address the back operation as well (then the index is decreased clear all responses above the current one)

Hi Teknowizard,
I am going to take your "ui" description literally and assume you really want to display a single question at a time, and I'm going to assume that you intend for the question to be displayed in the main area of the form (i.e., independently of the textbox docked to the bottom). Please correct me if that interpretation is not right.
So you have some method of showing one-question-a-time (textbox ?).
Maybe you have a timer controlling how long the question is visible ... whatever.
Now the user is typing their answer in the textbox : you are going to monitor the user's actions in the TextBox and at some point change the question.
There are many ways to do this, and I'll give you a few hints about design choices you can make with your user input textbox :
1. Multiline property of TextBox : will it be single-line or multi-line
2. AcceptsReturn property of TextBox : what will happen when the user hits the Enter key ?
3. AcceptsTab property of TextBox : what if the use enters tab ?
4. WordWrap property of the TextBox : if multi-line do you want to allow wrapping ?
Once you have experimented with and familiarized yourself with these properties, you can move on to Events of the TextBox.
Note that you could, by setting KeyPreview property of the hosting Form to true, handle key down/up/press events at the Form level.
I suggest you examine the following Events :
1. KeyDown
2. KeyUp
3. KeyPress
And consider the issue of what if the user clicks outside the TextBox : do you wish to make the Focus be restrained so the only thing the user can do is type in the TextBox : examine Events :
1. Enter
2. Leave
If you wish the user to "signal" when they are done entering an answer by some keyboard activity, you are going to need to write a Key Event Handler : start writing one now, and mess around with it, get familiar with KeyCode and/or KeyData properties of the EventArgs passed to a Key Event.
If you wish the user to "signal" they are done by some other means, well, up to you.
A few hours now of experimenting will pay big dividends for you in the future.
best, Bill

Take the jar of baby food out of the cupboard
get a pan of water
remove lid from jar
fill the pan 1/2 full heat on stove with the jar in the water
get a spoon from cutlery draw
when baby food is warm remove from the pan
use spoon to scoop some out
feed yourself
It's a joke Bill, a joke, honest it's a joke.....

Hi Mycroft, I don't know why I'm laughing  , but fully agree : that's funny !
My philosophy is : "why help a man to scream, when you can show him how to damn himself for all eternity."
best, Bill
p.s. there I was patting myself on the head (the one on my shoulders, I mean) for having done what I thought was a helpful thing. I thought, to use your metaphor, that I was telling the OP : "here's what you need to explore in order for your 'wisdom teeth' to come in so you can 'graduate' from pabulum."

It's a slow afternoon here and I seem to recall a Lounge rant against rude responders where you were given a hard time. It struck me a hilarious to see you attempting to spoon feed this person.
If I have you mixed up then I apologise but the rant and some of the reactions (Chris's reply sticky) has modified my response pattern, I now have to wait for some idiot to post a programming question in the Lounge to vent my sarcasm on.

Hi MyCroft,
Yep, you got me mixed up with someone else; I was the author of a strongly worded post[^] on the Site forum stating I believed people were frequently using requests for help to "take a dump on" posters on the technical forums, and this was hurting CodeProject, and was (is) just nasty pieces of work with no redeeming value.
Chris came out with the new guidelines soon after my post : of course, however, I do not believe my post was the "cause" of acton by Chris : I think he was hearing from many people on this same issue.
Don't you remember when you were a "newbie" in some technical arena, and you really didn't want someone to write your code for you, but you did need some pointing to what was really important to focus on so that you developed your understanding, were enabled to solve many problems, rather than just get a "quick fix" for a specific case you were not making progress with ?
When people have kindly replied to me here with helpful pointers when I have been stuck, I've always experienced that as "helpful enabling," not "spoon-feeding."
As I said in my long post on the Site forum : I'd like to see CodeProject, my favorite site in the whole world , my faithful old friend, my galaxy of revered gurus and teachers, have the same dynamic, evolving, kind of "tsunami" of sharing and interaction around problem solving for programmers that I see over on StackOverflow.
imho we can contribute to that partially by getting our jollies at our own expense rather than using people we don't know many of whom may not be "native" English speakers.
Let us, my friend, disprove the theory of humour espoused in the play "Comedians" by Joe Orton where he has the protagonist say, at one point : "the essence of humour is somebody else gets hurt."
best, Bill

I have managed to make use of the DwmExtendFrameIntoClientArea in Vista/7 to extend the glass effect into a form. However I cannot get this to happen on a form which is set as an mdi container. The glass portion just doesn't draw any more - it appears white. Note I'm not talking about the children inside the mdi parent, but on the actual main form itself.
Does anyone have any suggestions on how to get this working?

Anyone ever tried to get additional areas of glass on an mdi form?

Hello All,
Is there a way to change the background color of single word in textbox. I know it can be done in richtextbox, but i am looking for textbox.
Thanks

No way. Use RTB.

RTB is heavy for my scenario, i was thinking whether can be done by overriding OnPaint/WndProc?
Thanks

You can paint anything you want on any Control you choose, so the Form itself, or a Panel, would be fine. Why still use a Label if it doesn't do what you want? You still need to tell it somehow which parts need which colors.

What do you think base.OnPaint(e); would do for a Label?

text should be selectable.

I don't think OnPaint() contributes to selection.

You can't do this in the TextBox control. However, you could create your own control that derives from TextBox and override the Paint method to do whatever you wish. Of course you'd have to come up with some way of specifying which word(s) have different colour backgrounds. Seems like a lot of work when RichTextBox already does this.
while (e) { Coyote(); }

Hi
I have written a small UserControl that, at the moment, only overrides the OnPaint event without anything else. However, the content I am drawing in the control is sometimes larger than the display-area itself, so I want to implement scrollbar-functionality that allows the user to scroll if the content does not fit the screen.
I have googled a bit for this topic, but can not find any good information, and my book only tells me how to draw UserControls, not how to implement scrollbars. Any ideas where I can get started with this?
Appreciate any help
